My Journey into Data Structures and Algorithms (DSA)

Learning Data Structures and Algorithms (DSA) has been an exciting and enriching experience so far. As I dive deeper into core concepts like sorting algorithms, recursion, and linked lists, I can already see improvements in my logical thinking and problem-solving abilities.

Sorting Algorithms

Sorting is one of the fundamental concepts in DSA, and understanding different sorting techniques has helped me grasp how data can be organized efficiently. Some of the algorithms I have explored include:

• Bubble Sort – A simple yet inefficient algorithm that repeatedly swaps adjacent elements until the list is sorted.
• Selection Sort – An approach that selects the smallest element from an unsorted section and swaps it with the first element.
• Insertion Sort – Efficient for smaller datasets, this algorithm builds a sorted array by inserting elements in the correct position.
• Merge Sort & Quick Sort – More advanced techniques that use divide-and-conquer strategies for faster sorting.

Through these, I have realized the importance of time complexity and how different algorithms perform under varying conditions.

Recursion

Recursion is another topic that has fascinated me. Initially, it seemed a bit tricky to grasp, but once I understood the concept of breaking problems into smaller subproblems and using base cases, it became clearer. I practiced recursion through:

• Factorial Calculation
• Fibonacci Series
• Tower of Hanoi
• Binary Search (Recursive Approach)

Understanding recursion has also helped me in tackling problems that involve backtracking and tree-based structures.

Linked Lists (Singly & Doubly)

Learning about linked lists has been an eye-opener. Unlike arrays, which require contiguous memory allocation, linked lists provide dynamic memory usage. So far, I have worked with:

• Singly Linked List – Where each node points to the next node.
• Doubly Linked List – Where each node maintains links to both the previous and next nodes.

Implementing basic operations like insertion, deletion, and traversal has given me confidence in understanding pointer manipulation and memory management.

Conclusion

My journey into DSA has been insightful, and I can already feel an improvement in my logical thinking and problem-solving approach. Every new concept I learn pushes me to think critically, and I am excited to explore more advanced topics like trees, graphs, and dynamic programming in the future.

DSA is a skill that requires consistent practice, and I am looking forward to solving more problems and refining my understanding further!
